Confidence is compassionate and understanding. It is not arrogant. Arrogance is born out of fear and insecurity, while confidence comes from strength and integrity.
Anything can be achieved through focused, determined effort and self-confidence. If your life is not what you want it to be, you have the power to change it, and you must make the changes on a moment by moment basis. Live your priorities. Live with your goals and your plan of action. Live each moment with your priorities in mind. Act with your own purpose, and you will have the life you want.
